Rail fish plate, also known as rail joint or joint bar. As one of the railway components, the function of the rail joint is different from other rail components. Rail joint is a flat metal plate, usually used to connect two adjacent steel rails through several rail bolts.

The railway fishplates have holes drilled at the ends of the parts to be connected. There are some holes at the end of the railway track, which are used to align with the holes on the railway fishplate and are connected with rail bolts.

Generally speaking, rail fish plates are made of steel, but plastics and composite materials are alternative raw materials for insulated rail joints.

Types of Rail Fish Plate:

According to different applications, rail joints can be divided into many types. Typical rail joint types include common rail joints, insulated rail joints, non-standard rail joints and compromised rail joints.

1. Common rail fish plates

Common fish plate is made of general material Q235 steel, this kind of rail fish plate can be used for various types of rails. The appearance and weight of Common rail joints vary with the weight of railway tracks. The main types of Common railway fishplates are 4-hole and 6-hole.

2. Insulated rail joint

The railway insulating fish plate is made of thermosetting material, which has the characteristics of anti-rust, anti-corrosion, anti-ultraviolet, non-conductive, and non-magnetic. Insulated rail joints are generally used in railway sections or leaky sections near power plants. Insulated rail joints can effectively prevent leakage accidents.

Features of bonded insulated rail joints:

1) The maximum length is 60' and make sure to specify the length

2) Mainly used for A-490 bolts or Huck pins (6 / 8)

3) Conveniently used for worn rail or transition rail configuration

4) Microalloy rail joint

3. Non-standard rail joints

There are many types of non-standard rail joints in all rail joints. The section and speed of different railways determine the difference between certain rail joints and common railway fishplates. Generally, there are three types of non-standard rail joints with different weights, different pitches and different appearances.

4. Compromise rail joints

Compromise rail joints are different from non-standard rail joints. General compromise rail joints include joggled railway fishplates and railway turnout expansion joints. Compromise rail joints are basically customized, mainly used for turnout expansion joints or the appearance of some railway sections with special designs and requirements. Compared with other types of rail joints, compromised rail joints are difficult to machine.
